Anyone who is targeting 11.5:1 AFR on this engine must have stock in oil companies. Or just not know how to tune it.

On EFI cars, 11.5-11.7 was always the sweet spot if you were a forced induction engine. You could go leaner if the engine was knock free. Ive never moded or tuned a DI engine so that is just what I assumed.
